hand compartment of the bucket. l i hen right-hand compartment oi. the huchct comes suiiiciently filled, the bucket will to the right until it rests upon the stop and in this movement the upper end of the partition 69 will have rocked the lever 04-, causing the lever to ascend to a maximum height as the partition 69 reachee a vertical position and then to drop to its mini nuin height as the partition assumes: an inclination opposite to that shown in the drawing. The oscillation of the lever 0i, trill be t anamittecl through the link 03 to con. spond-- ingly oscillate the hell crank lever 102, and, as shown in Fig. 3, this oscillatory movement of the bell crank lever will move the tootplate 161 of the same out of contact with the pin 65 in the lower clutch member 01, thus permitting the con'ipression spring (H- to force this clutch member into engagement with the teeth of the upper clutch member. Such engagement of the clutch n'iemhers will cause the lower section of the vertical ehaft 47 to revolve and through the mite gears 46 the horizontal shaft, carrying the teeth rollers will be caused to corrcepiindingly revolve. Referring to the Fig. 5, it will be seen that a certain regulated amount oi the dry chemical which rests upon the lace ot the feed-roller will, by this movement, he caused to pass out through the aperture 37. As the apparatus is shown, the shaft M can make but a single revolution at one time, for in'm'iediatelj after the hell crank 10%? oacillated to the right, the drop ofjhe lower 01- will return it to its original position, and so as the pin 05 appri acheev original position, it will engage beneath the inclined surface of the foot ltll and, continued rotation of the shaft will move the pin along); this incline, thus forcing; the lower clutch member downward, until by the time the pin has reached. the position SliOWll in Fig. 3, the clutch teeth are completely out ot' engagen'ient. single tipg'iing movement. of the bucket 07 therefore opcratea to engage the clutch for a single revolutioi'u at the end of which it becomes automatically dinn- For each tipping movement of the bucket, therefore, the feed rolls 353 will have revolved some predetermined amount, dependent upon the 'atio of the miter gears 46. The tipping of the bucket, in turn, ie dependent upon the flow oi. water from the dividing box, that is to say, the time it takes for the bucket to fill suliicicntly to tip is a function of the rate ol' lion of the raw ater through the pipe 11. it will he iuulcretcod that after the bucket has tipped to the partition 60 will serve to direct the rot,

inc opt ation oil 1 oucltct is, ihereiore, an later iuitcnt on: lation, depcnde it in time upon the rate oi" flow of the watertln'ough the pipe ?2. it

will thus be ui'ideretood that the revolution of the feed rolls 35, by which is determined the feed of the dry chemicals is in direct proportion to the feed of raw Water through the pipe 11.

The second tlactor determining the relation hetween the feed of raw water and the feed. oi the chemicals from each receptacle, is the height of the opening 37 through which the chemicals are :led, and my invention is large y concerned. with a means for adjusting these openings. i-Eiounted on some conveniently, acce sihle part of the 'ameovorl: and as shown directly in front of the hoppers 31, 32 is the mechanical calculating, indicating and teed-regallating mechanism, generally indicated by the niuneral All. This mechanism comprises three concentric disks 80, Ell and 0:, and a pair ctanbincd regulating levers and pointers i i-f, and 84:, journnlciil to UriCllllll'tf about an axis concentric with teat ot' the disks, and connected to the links elf-l l) which the levers; 40 ll, controlling the sliding itea are ,n'iovcd.

Located centrally Within the movable scale 81 is a second fixed scale 82 having along its edge greduations oressing Weights of e (la ash necessary for treating a unit charge of raw-Water.

in order te illustrate the operation of my slide-rule, we will assume the following sample analysis of raw-Water:
